Arsenic biochemistry is the set of biochemical processes that can use arsenic or its compounds, such as arsenate. Arsenic is a moderately abundant element in Earth's crust, and although many arsenic c

…spectrometry by the same group found no evidence of arsenate being incorporated into the DNA of GFAJ-1. Arsenate esters, such as those that would be present in DNA, are generally expected to be orders of magnitude less stable to hydrolysis than corresponding phosphate esters. dAMAs, the structural arsenic analog…
Arsenic poisoning is a global problem arising from naturally occurring arsenic in ground water.
